Abstract
A disconnection device for surge arresters has a current-interrupting device which is suitable for interrupting the fault current once the voltage-dependent resistor in the arrester becomes conductive as a result of aging or overloads. This fault current flows through the common earth line of the associated arrester, which line forms the primary winding of a straight-through transformer which is built into the disconnection device. The secondary winding is connected to an electronic energy storage circuit which is independent of the mains voltage. A converter relay is operated by this energy storage circuit in a pulsed manner when a fault current of predetermined intensity flows to earth through the earth line. The converter relay can be either a monostable or bistable electromechanical relay, or an electronic relay (e.g. a thyristor circuit). When the relay contact is closed, an electromagnetic trip device (latching trip device) is operated by the energising current taken from the mains, which trip device trips the latching mechanism of the current interrupting device. Thereafter, the monostable converter relay reverts back to its original position again, or the bistable converter relay is mechanically or electrically reset to its original position, as a result of which the relay contact opens and the disconnection device is ready to switch on again via an operating device.
